A National Transportation Safety Board investigator plans to have a preliminary finding by the middle of next week about the crash of a powered glider in waters off north Kauai.
The crash Tuesday killed Kauai pilot Steve Sprague, 48, and passenger Ray Foreman, 53, of Vista, California.
Board investigator Jim Struhsaker said he interviewed several people and had some time yesterday to examine the wreckage of the aircraft P&M Aviation Ltd. Pegasus Quik.
Struhsaker said the wreckage was a "mess’ after hitting the water and it will be a challenge to determine what, if anything, broke while the aircraft was in the air.
He said he was unable to view information in a camera memory chip and that the chip will be sent to a laboratory to see if the information can be retrieved through other means.
He said the investigation also recovered a GPS device.
